REVERSIBLE WINDOW-SASH.

To all 'whom it may concern Be it known that I, CHARLES O'rro KUEHNY, citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Reversible Vindow-Sashes, of which the following is a specification.

This invention relates to reversible window sashes, all substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective lview of a lower window sash and the lower portion of the casing in which it is hung and certain parts associated with its reversal and closure at the sides to make the same air tight. Fig. 2 is an enlarged edge elevation of a sash supporting carrier and the safety plates or strips thereon and an inside view of the two sash strips which work with said carrier strips, face views of which respectively are seen in Fig. 1 and cross sections in closed and interlockcd relations in Fig. 4l. Fig. 3 is a perspective view, enlarged, of the middle portion of the sash, showing its edge and provided with a trunnion or pivot but not with the metal strips. Fig. t is a cross section of a sash and a sash supporting carrier equipped with strips respectively in closed and interlocked relations. Fig. 5 is a detail of the spring which holds the parts together in close working relations. Fig. 6 is a perspective view of one of the several sheet metal meeting plates, brokenat its middle. Fig. 7 is a vertical sectional elevation of the window sash and carrier on the line of their pivot connection and showing the tension spring in action as well as the relations of the ends of said plates to the said pivot or trunnion. Fig. 8 is a perspective view of the middle portion of one of the carriers and the plates thereon and interlapped at their ends about the pivot as herein fully described. Fig. f) is an inside view of the middle portion of one of the carriers with its plates fixed thereon and sections of the plates or strips that go on the sash at right angles thereto and showing the successive positions of the Specification of Letters Patent.

ends of said strips to each other about their common pivot as the sash is half way open.

The window sash is indicated by a and the casing in which it is set by c, and 'b represents a sash supporting slide carrier at each side on which the sash is pivoted and adaoted to he rotated and inverted for washing as well as for ventilation. fixed on the edge of the sash and extend freely through corresponding holes in the carriers and are engaged at their inner ends by springs s fixed to the carriers. These springs tend to hold the carriers and sash in close working relation with cach other in and through the intervening plates by which an air tight working engagement is made. It should he understood that the said carriers and the sashes correspond in length and always slide together, but the face of the carriers is flush with the face of the cas ing. This brings the sash within the casing in such manner as to clear the same at both sides when it is turned on its pivots. Now, in order to make a simple and effective working connection between carrier and sash I employ four sheet metal strips or plates 1, Q, 3 and 4t respectively on each side of each sash, which are rights and lofts as to the `two sides of the sash but otherwise are exactly alike. Thus, the shape and position 0f the said strips is clearly shown in Figs. 2 and il in which it is seen that each plate has a hack lapped outer edge 711,. with the immediate edge a thereof bent at right angles and adapted to enter and rest in a lmigitinlilial slot /t in sash and carrier respectively according to which it is connected with. Said flanges n and the slots It serve to make an absolutely air tight joint between said plates and their supports and screws or nails inserted through the 'flat overlapped portions m may he employed to tix the plates permanently in place. Each plate has a suhstantially semi-circular recess fr in its inner end which is seated against the trunnion (l, and the relation of the said plates to each other is such that the plates on the sash are adapted to slide beneath the plates on the carrier when the sash is folded or closed in the window. That is, as seen in Fig. 2, the

Trunnions (l are` plates l and 3 slide in beneath the plates 2 and 4 next to the carrier, and this is possible by reason of the projections on the said plates about said recesses being arranged as seen in Figs. 2, 7 and 8, particularly. For example, the said recessed meeting ends of the several plates show the recess r oli the median line of the plates with a relatively narrow single thickness projection a at one side and a partially doubled end y on the other side of said recess with the flange a to its extremity. Furthermore the projection af: is somewhat shorter than the proj ection y as shown herein, and the order of their arrangement requires that the shorter projection or end should come overthe longer projection y of the plate which is in endwise relations therewith, as plate 2 to plate 4, Fig. 2. In this connection attention is especially called to Fig. 9, wherein the order of arrangement of the said plates is clearly shown, and the plates or strips on slide o and those on the sash are in right angled relations, as when the sash is swung half way open. It might as well be inverted or so as to bring the top of the sash to the bottom and the outside of the glass to the inside in reverse position and not throw the interlapping ends or projections of the plates out of right working relations. In this connection it should especially be observed that each plate or strip has not only a free inner edge but that all said plates are free from said edge inward to the flange fr which is sunk into slot it and seals the union of said plate and the part which carries it against the creeping or passage of air across or beneath the said flange. Utherwise the. plates lie flat against their supports and fit closely when closed one beneath the other as illustrated in Figs. 4c and 7.

A. necessary peculiarity of relation between plates is seen in Fig. 8 where it is seen that the doubled edge 8 of each plate comes out flush with the edge of strip Z) while the single free edge 9 is inward from the oppo# site edge of said strip, and this is true of both plates 2 and t but they are reversed as to each other above and below the pivot center. rlhe points or ends a and y also are deep enough to extend practically the full width of pivot cl and are overlapped by this much to make an air tight relation about said pivot. 1t is obvious therefore, that so far as the passage of air through or between the said parts is concerned there is no such possibility. Furthermore, there is no extra part or piece of any kind necessary to make an air tight joint, and the said plates close like the blades of a pocket knife only much tighter. The spring s exerts a constant pull together as between the carrier b and the sash a. so that they are held in close working relation at all times.

Now, as a rsume, it will be seen that there are eight plates to each window sash, two above and two below, at each. side, and rights and lefts on opposite sides. The our on either side on sash and carrier are alike and interchangeable. rlhe flanges f/L are permanently embedded in the slots L, and theinner ends of the plates are in a sense bifurcated or divided by the recesses 7" into two projections m and y which are superimposed or built up one upon the other about trunnions d in such way as to' always have the sash carried plates 1 and 3 close in beneath or behind the strip carried plates 2 anda next tothe surface of the carrier'. To this end the points of the sash plates are held initiallyv beneath the carrier plates in whatever position the sash maybe. Hence when the sash is to be restored after having been opened the remainder of edge 9 simply follows the point x which is permanently in the lead and the closure must follow of necessity. The said plates are complete to effect closure and are dependent on no other means.

W hat l claim is:

1. 1n combination a sash, a supplemental stile, a central pivot connecting said sash and said stile, plates lixed on said sash and stile having recesses with side projections at their adjacent ends abutting said pivots, said projections being overlapped and underlapped successively by the corresponding .portions of the opposite plates about said pivot. j

2. A window sash and a fixed casing, a carrier for the sash slidably mounted in said casing and provided with a trunnion at its middle on which the sash is pivoted and Jfree to swing into a completely reversed position, thus bringing the outside of the window into a vertical position within the window Jfor cleansing, and fixed plates on said sash and carrier, respectively, substantially in alinement with each other, said plates having each a substantially semicir cular recess fitting closely against said pivot, said plates each having projections at the sides of said recesses overlapping about said pivots, one of said projections on each side of the sash entering beneath the similar projection on the supplemental stile and the other projection on said plate overlapping the other plate on said stile.

8. A window sash and sliding carrier therefor having pivots on which the sash is adapted to be bodily inverted and the said sash and carrier having separate sheet metal strips on their edges provided with recessed inner ends overlapped about said pivots and the outer edges of said plates having doubled flanges at right angles to the body thereof their full outer length and extending past the said pivots in each plate, Where- In testimony whereof I afHx my signature n presence of two Witnesses.
